Effects of PbO Loss on Microstructural Development and Properties of PLZT Ceramics

Abstract

Commercial lead lanthanum zirconate titanate (PLZT) ceramics were annealed in air at the temperatures between 970 to 1080 C resulting in various amount of lead oxide loss. The fracture surfaces of the ceramics gradually change from intergranular mode to transgranular mode with increasing PbO loss. Both dielectric and piezoelectric properties degrade with development of new phases due to PbO loss. The related mechanisms for these results were discussed.
